Microsoft Won't Patch 20-Yr-Old SMBv1 Vulnerability (You Should Just Turn the Service Off) (onmsft.com)
An anonymous reader shares a news post: Following the recent WannaCry and Petya ransomware attacks, Microsoft recommended all Windows 10 users to remove the unused but vulnerable SMBv1 file sharing protocol from their PCs. This is because both variants of the ransomware actually used the same SMBv1 exploit to replicate through network systems, even though it seems that Petya mostly affected Windows PCs in Ukraine. Anyway, if you haven't turned off the protocol on the PC already, you really should: Not only because new WannaCry/Petya variants could once again use the same vulnerability again to encrypt your files, but because another 20-year-old flaw has just been unveiled during the recent DEF CON hacker conference. The SMB security flaw called "SMBLoris" was discovered by security researchers at RiskSense, who explained that it can lead to DoS attacks affecting every version of the SMB protocol and all versions of Windows since Windows 2000. More importantly, a Raspberry Pi and just 20 lines of Python code are enough to put a Windows server to its knees.
We hear much nowadays from the homosexual community about being "born gay." TV talkshow hosts, the newsmedia and medical professionals have bought into the deception that some people are naturally born HOMOSEXUAL and can't help it. Nothing could be further from the truth.
To say that some people are born homosexual is to say that God makes mistakes. If God creates a man (with a man's reproductive organ), but that man has God-given natural sexual desires for another man, then God made a mistake. The Bible plainly states in Genesis 1:27, "So God created man in his own image, in the image of God created he him; male and female created he them." There is nothing in the Bible about two men getting married, or two women. Same-sex marriage is sinful in the eyes of God.
God doesn't make mistakes! No one is "born gay." God created male and female, and they have natural sexual attractions one for the other, because they have male and female reproductive organs, respectively. The very idea of two men having sexual relations is against nature. In fact, the Word of God states this in Romans 1:24-28. Romans 1:26,27 state: "For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature: And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet." Clearly, the Bible teaches that heterosexual attraction is natural; BUT homosexuality is abnormal and against nature.
God doesn't make mistakes! No one is "born gay." If you tell me that some people are "born gay," then you are saying that my God makes mistakes, and my God doesn't make mistakes. Why would God give two men a "natural" attraction one-for-the-other, but then they can't mate and reproduce because they both have male reproductive organs? That would be absurd. If homosexual attraction is "natural," then God made a mistake. God doesn't make mistakes! The truth is that no one is "born gay." It's a choice. Homosexuality is a vile lifestyle of lust, Godlessness and shame that one CHOOSES to live.
Job 8:3 and 13-14, "Doth God pervert judgment? or doth the Almighty pervert justice? ... So are the paths of all that forget God; and the hypocrite's hope shall perish: Whose hope shall be cut off, and whose trust shall be a spider's web."
I don't believe it is ever right to bash gays, but we have a duty as Christians to speak out against the horrible sin of homosexuality. We ought not condemn anyone on a personal level for their sins and mistakes, for God is the only Lawgiver and Judge. James 4:12, "There is one lawgiver, who is able to save and to destroy: who art thou that judgest another?" James 5:9, "Grudge not one against another, brethren, lest ye be condemned: behold, the judge standeth before the door." Yet, the Bible teaches for Christians to refute (Greek: elencho, "expose") all works of darkness. Romans 1:24-32 condemns the sin of homosexuality.
We don't have to condemn sin because the Bible already condemns the whole world. We are all sinners (Romans 3:10,19-23). Ephesians 5:11, "And have no fellowship with the unfruitful works of darkness, but rather reprove them." There is a clear-cut line between preaching against sin as God commands verses condemning someone to be vindictive or mean. The Bible teaches that every work shall be brought into judgment. Ecclesiastes 12:14, "For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil." God will hold all men accountable for each and every decision they make, and recompense them for the good and for the evil.
Why doesn't Microsoft patch the OS so that SMB1 is disabled entirely? I mean MS already shoves all sorts of crap down your throat anyways, why can't that unshove shit?
Most of HP's multi-function printers with Scan To Network only support SMB1. When will they issue a firmware update that adds support for SMB2?
Looks like the Pwnie Awards for "Lamest Vendor" was given to the wrong "vendor". Wilfully leaving millions of people open to an exploit that is in active use is just beyond lame.
Well, for what it's worth, at least the Windows systems described in the summary manage to boot properly, to the point of having network connectivity and running services.
I can't say the same for my Linux systems that run a distro that uses systemd. I've had those systems fail to boot much too often thanks to problems with systemd.
Maybe this is just systemd doing me a favor and protecting my Linux systems, though? After all, a Linux installation that doesn't boot far enough to mount the filesystems properly likely won't have network connectivity, and likely won't have any services running that might be susceptible to attack.
More importantly, a Raspberry Pi and just 20 lines of Python code are enough to put a Windows server to its knees.
Well, isn't your run of the mill screen saver enough to do that?
You shouldn't use outdated standards. I thought this was already decided. Let me go update my router so that it'll fix a bug in WEP. That'll make it secure.
looks like god made 1 mistake...
Apache has the same vulnerability and they never really came up with a good fix for it.
Like Robert Graham describes in http://blog.erratasec.com/2017..., it's a type of attack that can be perpetrated against any service on the internet.
Solutions:
- Build a proxy service (per the article) that parses input before passing it to $SERVICE.
- Do not put it on the internet (i.e. firewall).
Is SMB open by default in Windows Firewall anyway? If anything, pooh-pooh Redmond for that. I know, I know, millions of affected hosts.
They should just send an update that disables it for all users. It would have to be no more a pain due to the repercussions of not disabling it.
Seriously though, there is an awful lot of questionable things (to me) that Microsoft does on a regular basis. But doing something like this would be A super inconvenient, and B, force a lot of other vendors to up their standards as well (pun potentially intended).
I couldn't see the move as any more disastrous as entire hospitals going offline... I dunno, this is just one guys opinion... flame away!

Yeah, he kept SMBv1 turned on so Jesus could stream his tranny porn collection on the home network.
Because SMBv2 on android is apparently still difficult. With ES File Explorer, you need to install some crappy game to get SMBv2 support and it's spotty at best. Not everyone likes to run a streaming server (that actually have client-like, full screen interfaces), just have a share or two and access it via SMB from all kinds of devices. Maybe there'll be a Windows port of SAMBA to use a non-vulnerable version of SMBv1.
When the copyright term is "forever minus a day", live every day like it's the last.
The trouble is that lots of software still requires it. Probably why MS don't turn it off via an update.
Remove it just to see it reappear after the next windows update.
sudo rm -r -f --no-preserve-root /
By "the service" do you mean SMB? The threat is descirbed as affecting all versions of SMB, but nearly all of the tech writers describing the bug are suggesting turning off SMBv1. Is no one actually paying attention to what the authors are saying, or am I missing something?

Wankers
There's a patch for this.

aaaaaaa
Won't this leave all Windows machines vulnerable to any other exploit that would gain access to the device, potentially turn it on again, and allow the ransomware to do its damage?
It would be better to remove SMB1 support entirely, or patch it if that's too difficult for MS.
Fuck off, there's a good scumbag.
Agreed, there is a huge lot of older but still functional equipment that only talks SMB1. Microsoft has put together this list, and it surely isn't everything: https://blogs.technet.microsoft.com/filecab/2017/06/01/smb1-product-clearinghouse/
https://www.freebsd.org/
OS X still has such miserable SMB client we are stuck with SMB1/CIFS to maintain some semblance of reliability and speed.
See subject & for the solution - SMB Ports 445/139 (TCP) & 137/138 (UDP) protection via:
Disable SMBv1 on the SERVER, configure the following registry key:
Registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters Registry entry: SMB1
REG_DWORD: 0 = Disabled
REG_DWORD: 1 = Enabled
Default: 1 = Enabled
Enable SMBv2 on the SERVER, configure the following registry key:
Registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters Registry entry: SMB2
REG_DWORD: 0 = Disabled
REG_DWORD: 1 = Enabled
Default: 1 = Enabled
---
Disable SMBv1 on the CLIENT, run the following commands:
sc.exe config lanmanworkstation depend= bowser/mrxsmb20/nsi
sc.exe config mrxsmb10 start= disabled
Enable SMBv2 & SMBv3 on the CLIENT, run the following commands:
sc.exe config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi
sc.exe config mrxsmb20 start= auto
---

(THIS HAS BEEN PATCHED but you can protect this way too & it works...)
Not sure if this works in a "mixed-mode" network though (check MS link) using older Windows (e.g. XP/2000 etc.).
APK
P.S.=> For a SINGLE 'standalone' non-networked PC (no home network/LAN but TCP/IP connected online) turn off Server & Workstation services.
That shuts off any "handles" (port 445) this thing propogates thru + turn off NetBIOS over TCP/IP in your internet connection & uncheck/disable Client for Microsoft Networks + File and Print Sharing. Port 139 & 445 always pop up issues over time. It also makes your packet trains smaller (no encapsulation of LanMan)
I covered all this 11++ yrs. ago in a security guide I wrote for users with a single system & apparently, its advice STILL STANDS THE "TEST OF TIME" https://www.google.com/search?hl=en&source=hp&biw=&bih=&q=%22HOW+TO+SECURE+Windows+2000%2FXP%22&btnG=Google+Search&gbv=1/ vs. even today's threats like this one.
* This effectively makes this threat a non-issue + saves you CPU cycles/RAM & other I/O wasted on services you don't NEED as a single PC user only... & you don't. They're just wastes with a single PC really. Many services are (covered in guide above based on CIS Tool guidance (who took fixes to their ware from "yours truly" too, no less)) & again, no more encapsulated packet bulk... apk
There is a switch and service to disable User Experience (not send into to MS). This does nothing, one must disable them in the Task Options.
No remote access is the same way
Autoruns https://docs.microsoft.com/en-... allows you a one click to stop method. BUT could take many areas the same programs is turned off - I have always disabled "Windows Mail" I've 0 use for it. It must take some 20 disables - there obvious.
SMB is a one stop area.
Remove the SMB service from the ISO before install.
Open ISO, remove said components from ISO, install
Use NFS.
American idiots. It's "BRING a Windows server to its knees"...
